Which atomic model shows the atom as a positively charged sphere with negatively charged electrons spread throughout
tankabanditka [31]

Answer:

B) Thomson's Model

Explanation:

Dalton's Model simply consisted of small spheres that represented atoms, and Bohr's model had a nucleus in the center with electrons orbiting in strict orbits, not randomly spread throughout. Thomson's plum pudding model, however, had an overall positively charged atom with many electrons spread throughout. If you search up "Plum Pudding Model" you can visually understand this.

A compound is found to be 38.76% calcium, 19.97% phosphorous and 41.28% oxygen. What is the empirical formula for this compound?
motikmotik

The empirical formula is Ca₃P₂O₈.

<em>Assume</em> that you have 100 g of the compound.

Then you have 38.76 g Ca, 19.97 g P, and 41.28 g O.

Now, we must convert these <em>masses to moles</em> and <em>find their ratio</em>s.

If the number in the ratio are not close to integers, you <em>multiply them by a numbe</em>r that makes them close to integers.

From here on, I like to summarize the calculations in a table.

<u>Element</u>  <u>Mass/g</u>     <u> Moles  </u>      <u> </u><u>Ratio </u>    <u>   ×2    </u>   <u>Integers</u>  

     Ca       38.76      0.967 07     1.4998   2.9995         3

     P         19.97       0.644 82     1             2                   2

     O        41.28       2.580 0       4.0011   8.0023          8

The empirical formula is Ca₃P₂O₈.
